Here's why:
* Geology is the study of Earth's physical structure, its history, and the processes that shape it. This includes:
* Plate tectonics: The movement of Earth's crustal plates, which causes earthquakes, volcanoes, and the formation of mountains and oceans.
* Erosion: The wearing away of Earth's surface by wind, water, and ice, which changes landforms and transports sediment.
* Weathering: The breakdown of rocks, soils, and minerals by physical and chemical processes, changing the composition of the Earth's surface.
* Volcanism: The eruption of molten rock (magma) from Earth's interior, which releases gases and adds new material to the surface.
* Sedimentation: The deposition of sediments, like sand, silt, and clay, which form new layers of rock over time.
While other fields like chemistry, physics, and biology contribute to understanding Earth's processes, geology is the primary field that focuses on the overall changes in Earth's composition.
